Application filed May 14,

My invention relates tolubricant cellars ot' locomotive driving boxes, and its object is to provide a cellar of simple, substantial, and inexpensive construction, which will be easily insertible in, and removable from, a driving be of ordinary type; which will, by its capacity of being readily and quickly opened, without disturbance of its connections to the driving box, facilitate its replenishment with lubricant, as from time to time required, with an economy of time, and avoidance of liability to loss of parts; and which will remain securely closed while lu-- brie-ant is being supplied to the journal.

The improvement claimed hereinafter fully set forth.

In the accompanying; drawing: Figure l is a view, in perspecti e, of a locomotive t'ranie p dest l and. driving box, with a lubricant cellar embodying my invention, shown open for replenishment oi: lubricant; and, F 2, a vertical longitudinal section through the cellar, in closed position.

In the practice of my invention, referring descriptively to the specific embodiment rent which is herein exemplified as applied in connection with a driving axle box, of the ordinary construction, fitted in pedestal jaws, 1, of a locomotive frame, 1, I provide a lubricant cellar, indicated, as a unitary member, by the reference numeral, 4-, which is adapted to lit between the legs of the box, 2, and is of rectangularsection, the body of said cellar comprising a bottom plate, l vertical side walls, 4P, and a vertical back end wall, at", said side and back end n L a walls being integral with the bottom plate.

The outer end 01": the body is closed by a 2 end wall, r which is detachably connected to the side walls, l of the body. 1 nee pivot lugs, d having; inclined outer P, and horizontal bottom faces, l are the bottom plate, 4.

7 rent end wall, 4-, of the lubricant cellar, hinged to the body thereof, and terms a lid for the cellar, which enables it to be replenished or repaclzcd with lubricant, as may, rom time to time, be required, without detz'rching' or removing, it from the drivbox. 2. The lid, 1-, is hinged to the pivot lu 7, 46*, at the front of the bottom wall of the cellar, by a pivot pin, 5, and held in open and closed positions by two plate springs, 6. Each spring has an intermediate portion, which bears on the inner side i926. Serial No. 109,059.

of the lid a straight bottom portion, which extends through a recess at the bottom of the lid, andbears upon one of the cam faces, 4

of one or the hinge lugs; and a top portion,

disposed at substantially a right angle to the bottom portion, and extending through a slot, which is disposed above the recess, and extends from the inner to the outer side of the lid. The top portion of each spring;- terminates in an upwardly extending flange, or lug, which bears on the outer side of the lid, above the slot. It will be seen that the described construction obviates the use of rivets to hold the spring in place.

Perforated lugs, 4-, are ,iormed on the sides ot the lid, atits top, to serve as grips for facilitating its opening'and closii and lugs, ll", are also formed in it, below the lugs, 4t A locking pin, 7, is passed through perforations in the lugs, l of the lid, and in lugs, 4, on the side walls of the cellar, which align with the lugs, 4 to prevent possibility of accidental opening of the lid, due to lack of suflicient tension in the spring, 0.

The lub icant cellar of my invcnti on which herein set forth is dil'lerentiated from, and of greater practical advantage than, those before known in the art, in the particulars of being; of simpler and cheaper construction; possessing the capacity of ready replenishment whenever d sired, without detachment from the during box or manipulation of other members; and avoid ing the loss of, or injury to, other parts of the drivin box structure, in application,

. '0 operation, or renewal.

i claim as my invention and desire to secure by Letters Patent:

In lubricant cellar, for axle boxes, the combination of: a receptacle, having one end open, and a hinge lup; at said end, the lug having closing the open end of the receptacle, comprising a hinge lug,and two hinge recesses, one disposed above the other;-a pintle connecting the hinge lugs; and a plate spring,

havin an intermediate portion bearing on the inner side oi the lid, a bottom portion projecting; through the lower recess in the lid, and bearing on one of the cam faces of the hinge lug, and a top portion projecting into the upper recess in the lid, and locking the spring in position.
